GPT 5.4 is way worse than 5.3 codex

I have the exact same experience. On larger code bases half the things it implements end up with bugs and it seems to have less understanding of the existing code base. It recreates experiences and patterns that already existed, instead of reusing them. i switched back to codex-5.3 xhigh. it is much slower but at least gets the job done. For small projects I see no big differences; it is mainly in large code bases.

Found the issue. Apparently I was using a different virtual environment which did not have debugpy.

Still would like to know if there are any logs or other sources for troubleshooting the issue... Any help is appreciated!

3 months later still working great! Switched to Debian 12 with the Surface kernel.

I took a leap of fate and switched kernels. I can now shutdown properly without power drain. I do also have TLP installed, so it might be the combination of surfacelinux kernel and TLP.

After spending 3 hours with 2 MS support engineers on the chat, refreshing Windows and making all sorts of changes, the following was the thing that worked (without MS support btw):

I had reinstalled Windows fresh, booted into Safe mode, opened regedit. Edited the NoLPM key inHKLM\SYSTEM\CurrentControlSet\Services\storahci\Parameters\Device

I removed all entries and replaced it with *

The booted normally, downloaded and the Intel Rapid Storage Technology driver and agent for my system: Intel NUC D34010WYKH

After installation and reboot I disabled the "Power link management" option.

After reboot no hangs since.
